scription anddrawings, and will be partioularly polnted out in the appended claims.

In Figs. 1 to 4, inclusive, is shown a disotally mounted top 11, which may havea carpet covering, and transparent sides 12 and front 13, the top 11, in the front portion thereof, having an elongated slot 14 for the reception of an-upwardly'extending outlet member15 of a triangularly shaped receptacle 16 secured in the box and adapted to hold dust or cork 17 drawn therefrom by the motor-propelled fan 18 of the vacuum cleaner 19. The dust or cork is drawn upwardly through the outlet 15, cleaner nozzle 20 fitting thereover, fan casing. 21, and forced by the fan and gravity throughthe bag 22, hose 23' and funnel .member 24 back into the'receptacle 16. The nozzle member .24 extends through the rear of box 10 and through the apex portion 25 of the recepta .cle 16, said nozzle member extending forwardly and downwardly within the receptacle 16 to deposit the dust or cork properly to prevent its heaping up in the rear of the receptacle, and also to place the same in a convenient and efiicient ran e of the fan 18 so that it can be drawn effectively. By experiment it has been found that the best results are obtained with a triangular receptacle 16 as shown, the fan acting most effectively under these conditions. The cover 26 of the receptacle 16 is held in place by a spring 27 secured to the inside of rear of'the box 10. The vacuum cleaner 19 in. thiscase is fixed to the top of the box 10' by any suitable means. The bag 22 may be transparent or have a transparent portion 22*. The" motordriven fan 18 is driven intermittently .means of this arrangement the action of the vacuum cleaner-fan 18 in drawing the dust from any object is clearly pictured.

. 1 Attention now is directed to the modified so far as the observer can see, and then i D form or the traveling 'form ofvacuumhereafter we will describe the control parts. cleaner display device shown in Figs. 5 to 13, inclusive. The vacuum cleaner proper '33 is moved forwardly and rearwardly over the top 34 of a box 35, having a carpet covering, by an electric motor 36 mounted within' said box. The driving connection between the motor 36 and vacuum cleaner 33 includes a shaft 37 havinga long pulley '38 mounted between theshaft bearings 39. Opposite the pulley138 are three pulleys 40, 41 and 42, pulleys 40 and 41 being loosely mounted on a shaft43, the other pulley 42 beingfixed to said shaft. An open belt 44 and a crossed belt 45 passing around pulley 38, are respectively adapted to drive the vacuum cleaner forward and backward over the box when passing around tight pulley 42. thr'eadedportion 46, on which and by the actuation of which a nut 47 travels. Secured to this nut is a bent metal strap '48 which extends out through an elongated opening 49 in the side of the box and is connected to the body of the vacuum cleaner 33in any suitable manner. Thus, through the connections described, the vacuum cleaner 33 may be driven forwardly and backwardly over the box 35 by the electric motor 36. The shaft 43 is ournaled in bearings 50, to the supports of which are secured brackets 51 and 52, in which a belt shifting rod 53 is slidably mounted. Se-- cured to ,this rod are stop members 54 and 55, by means of which the belts 44 and 45' are shifted by the forks 56 when the slidably mounted member '57 of arm 58 secured to nut 47 compresses-the springv 59 or 60 against said stop members 54 and 55, respectively. The springs 59 and are provided to give a snap action in the shifting of the belts. Secured to the front of the nozzle 61 of the vacuum cleaner is a dust or cork containing hopper 62 having a lower hinged door 63 held closed under'certain conditions by a suitably .supported spring 64. Secured to the door is the bent arm 65 of the armature 66.of an electro-magnet 67 the armature having a vertically extending arm 68, said armature 66 having an opening therethrough for a suitable guiding member '69 having a'limiting stop member 70.. When the coil 71 of the magnet has an electric currentpassed therethrough, the magnet is energized anddraws its armature 66 down and therefore the door 63 with it, holding the door inopened position against the action of spring 64 as long as current is passing through said coil. The vacuum cleaner has its regular electric 'motoro72 (see Fig. 13) for driving the suction fan 73 mounted in casing 74. a

Mention will be made at this point of the operative movements of the vacuum cleaner The shaft 43 is provided with a long n the first forward stroke from left to right over the box 35 of the vacuum cleaner 33, the hopper door 63 will be open to distribute or scatter dust, cork or the like over the surface of the box top 34, it being underof this first backward stroke electric connections are established to operate the vacuum cleaner fan 73. During the second .forward and second backward strokes the fan 73 continues to operate, to draw. the dust or cork from the top ofthe box up through nozzle 61, forcing it through the bag 75 and hose 76 back into the hopper 62. At the end of the second backward stroke the fan motor electric connections are broken, there-\ by stopping the fan 73, and connections are 'inade for energizing the electro-magnet 67 again to open door 63 preparatory to distributing the dust or cork again over the top of the box on the next forward stroke.

This cycle of operations gives to the obg5- server'a-comprehensive and intelligent understanding of the operation and effective- I ness of a vacuum cleaner.

Consideration will now be given to control features by means of which the elec- 10 trical connections are made, broken and timed. Mounted within the box 35, to the left-hand side, is a metal bracket '77 having bearing portions 78 (see Fig. 9) in which a metal shaft 79 is rotatable. portion of .this shaft a fiber disk 80. (see Figs. 9 and 11), with four peripheral teeth 81, is secured by a metal pin 82 passing completely through the fiber disk 80 and metal shaft 79 and making electrical con- 11 tact with spring metal contact fingers 83 and 84 secured to oppositely arranged teeth 81. These fingers 83 and 84 are adapted to make contact'with a stationary contact 85 mounted on but insulated from bracket 77. 11

By means of this arrangement an electric circuit may be made (see Figs. 6, 9, 11 and 13). from one side 86 of a( supply circuit through conductor 87, bracket 77, shaft 79,

At the end of the first 75 To the lower pin 82, contact fingers 83 or 84, stationary contact 85, conductor 88, fan motor 72, through conductor 89 tothe other side 90 of the supply circuit for operating the vacuum cleaner fan 7 3;

The circuit, including the electro-magnet 2 67, will now be considered. Loosely mount,- ed on shaft 79 and electrically connected thereto, is a contact 92 adapted to make contact with a contact finger 93 (see Fig. 10). This contact 92 is carried by a fiber disk 94 having four teeth 95. The disks 80 and. 94 are relatively movable,-the disk 80 being fixed to shaft 79 and disk 94 being loosely At the right-hand end mounted thereon. of the travel of nut 47 is another bracket 96, in which is mounted a shaft 97 carrying a fiber disk'98 with four teeth 99, an electrical contact 100 being carried by said disk. 98 and Joeing electrically connected to said shaft 97. Thiscontact is adapted to pass into engagement with a contact finger 101.

' To complete the electric circuit of the electro-magnet, contacts .92 and 93 must be in engagement and contacts 100' and 101 also must be in engagement. ThIS circuit is traced from supply line 86, conductor 87,- bracket 77, shaft 79, contact 92, finger 93,

conductor 102, magnet coil 71, conductor 103', finger 101, contact 100, shaft 97, bracket 96, conductor 104 to the other side 90 of the supply line.

Electrical engagement between the various electrical contacts and their contact fingers is controlled by five fingers 105, 106,

107, 108 and 109, fingers 105 and 106 being adapted to engage teeth of fiber disk 94 to rotate the same, fingers 108 and 109 being adapted to engage teeth of fiber disk 98 to rotate it, .and finger 107 being adapted to engage fiber disk 80 to rotate it. These fingers are carried to the left and right by,

thetraveling nut 47. The disks are provided with specified numbers ofteeth and a certain number of cotiperating actuatlng Pawls 110 are provided to movements of the disks.

The complete operation of the device will now be-considered. Let it be assumed that the vacuum cleaner 33 has just moved into prevent reverse its extreme left-hand position, as shown in Fig. 5, the traveling fingers 105 and 106 having consecutively engaged adjacent teeth of disk 94 to move. contact 92 into engage:

ment with contact finger 93 to complete the circuit of the electro-magnet, and traveling finger 107 during the same time moving disk 80 one step to separate contact 84 and contact finger 85, thereby breaking the fan motor circuit. From this extreme left-hand position the vacuum cleaner makes its first forward movement to distribute dust over the top' of box 35. This -means that the hopper door 63 must be openand that the fan motor 72 must notbe operating. In other words, the circuit of the'electro-magnet is completed, the electro-magnet energized, andthe door 63 therefore in open position, while the circuit of the fan motor is broken by both fingers 83 and 84 beingout ofen-' gagement with stationary contact finger 85. The motor 36 being'permanently'connected to its source of supply, moves the vacuum cleaner bodily across the top ofthe box 35, whereupon,-during this first forward stroke,

the-top ofthebox 35. fingers are provided. for timing purposes.

the dust or cork falls out of the hopper 62 and is distributed. Near the end of this forward stroke the traveling fingers 109 and 108 consecutively engage adjacent teeth of. disk 98-, first separating contact 100 and'contact finger 101 to break the circuit of the electromagnet and permitting the spring 64 to close door 63, and then advancing the disk 98 and contact 100 one step further. At about the same time, or a little later, the slidably mounted member 57 passes into engagement with spring 60, and shortly thereafter causes, with a snap action, belt 44 to shift from tight pulley 42 to loose pulley 41 the electro-magnet, and then advancing the disk 94 and contact 92 another step. At the same time traveling finger 107 engages one;

of the teeth of disk to move contact 83 or 84 into engagement with contact finger 85 (see Figs. 9, 11 and-13), thereby completing the electric circuit of the fan motor 72 to operate the fan 73 to draw the dust from At about the same time also sliding member 57 presses against spring 59 to cause,-with a snap action,. belt 45 to be shifted from tight pulley 42 to loose pulley 40 and belt 44 to be shifted from loose. pulley 41 to tight pulley 42. This causes the.

vacuum cleaner to move bodily on its second boX through nozzle 61, forcing'it through I the bag 75 and hose 76 back into the hopper 62. At the end of the second forward stroke,

forward stroke, during which stroke the fan 73 draws thefdust from the top of the fingers 109 and 108 again advance disk 98 and contact 100 two more steps, placing contact 100 again in engagement with contact finger 101. The belts also are shifted to reverse'the movement of the vacuum cleaner.

On the second backward stroke, the fan 73 continues todraw the dust from the top of the box 35, leaving it in a perfectly'clean v.

ward stroke traveling finger I 107' again condition. At the end of this second backforces disk 780v around another step and thereby separates eithercontact 83 or 84 and contact finger 85, thereby breaking the electrio circuit of fan motor 72,-a'nd traveling fingers 105 and 106 consecutively advance disk 94 a step each, placingcontact 92again in electrical engagement with contact finger 93, thereby completing. the circuit-of the electro-magnet to open'the hopper door preparatory to again distribute the dust or cork over the top of the box 35 upon the next forward stroke of the vacuum cleaner, the vacuum cleaner having been reversed in the usual manner at the end of the second backward stroke. This cycle of action gives a comprehensive idea of the efi'ectiveness of a vacuum cleaner, and intelligently displays the action of the same. The operation throughout is automatic.
